This little light is typical of the large number of small LED torch style lights available now, but it's one of the nicest made we've seen.
The beam isn't powerful enough to ride off-road with, but it'll get you along the road/path on the way to and from the serious stuff. It lasts pretty well too and its compact size leaves your bar uncluttered.
It's had some horrible weather chucked at it and handled it fine - and the big button on the back can't be missed, however cold your fingers are. The thumbwheel tightened mount has a QR slot to speed up fitting, too. The only downside is its reliance on CR123A batteries, which are expensive, and not as easy to find as AAs, but with run times this long things could be worse.
